This study was undertaken to develop knowledge of ultrasound characteristics of germ cell testicular neoplasms, associate these characteristics with histopathologic tumor types, and lay a foundation for study of ultrasound findings in benign versus malignant testicular lesions.
The medical records and ultrasound images of 107 patients with testicular tumor were reviewed. Demographic and clinical characteristics and ultrasound findings of patients with seminoma were compared to those of patients with non-seminoma.
55 patients had seminoma (1 bilateral) and 52 non-seminoma. Ultrasound images of seminoma were more often hypoechoic, homogeneous, and lobulated than those of non-seminoma (p < 0.001). Images of non-seminoma were more often heterogeneous and cystic (p < 0.001). There was no difference in tumor size, multiplicity, presence of calcium or lesion margination. Testicular microlithiasis was more common in seminoma (p < 0.02).
Careful analysis of ultrasound images can permit an educated assessment of testicular tumor histopathology.
本研究旨在增进对睾丸生殖细胞肿瘤超声特征的了解，将这些特征与组织病理学肿瘤类型相关联，并为研究睾丸良性与恶性病变的超声表现奠定基础。
回顾了107例睾丸肿瘤患者的病历和超声图像。比较了精原细胞瘤患者与非精原细胞瘤患者的人口统计学和临床特征以及超声表现。
55例患者患有精原细胞瘤（1例双侧），52例患有非精原细胞瘤。精原细胞瘤的超声图像比非精原细胞瘤更常表现为低回声、均匀且分叶状（p < 0.001）。非精原细胞瘤的图像更常表现为不均匀和囊性（p < 0.001）。肿瘤大小、多发性、钙化情况或病变边界无差异。睾丸微石症在精原细胞瘤中更常见（p < 0.02）。
仔细分析超声图像有助于对睾丸肿瘤组织病理学进行有根据的评估。
